摘　　要：‘星光’是从骏枣变异单株中系统选育出的高抗枣疯病新品种。在太行山枣疯病重发区,将其高接到病树上能正常生长结果。‘星光’果实大(22·9g),制干率高(56·4%),既可直接作为抗病品种进行栽培,也可用于染病植株和感病品种的高接改造。‘Xingguang＇ , a new cuhivar of Chinese jujube （ Ziziphus jujuba Mill. ） with high resistance to jujube witches broom disease （JWB）, was selected from the variations of ‘Junzao＇ , an old local cuhivar, using a high-intensity screening method established by the authors, grafting the healthy scions of the germplasm to be checked onto seriously diseased trees. In Taihang mountain with heavy JWB, the disease rate of ‘Xingguang＇ kept 0 and 100% of the diseased trees reconstructed with it recovered normal fruiting. Its fruit is big （22. 9 g） and suitable for making dry fruit （drying rate 56. 4% ）. It not only could be cultivated directly as a high-resistant cuhivar but also used to reconstruct the crown of diseased trees by grafting.
